Fontainea picrosperma, commonly known as the blushwood tree, is a rainforest tree in the family Euphorbiaceae endemic to Queensland in Australia, where it grows on the Atherton Tablelands. [2]
An anti-cancer drug known as EBC-46 has been developed from an extract of the fruits of Fontainea picrosperma. Trials have shown that it has activity against four different types of tumours, including basal-cell carcinoma, melanoma, squamous cell carcinoma and breast adenocarcinoma. The fruits are toxic to humans if eaten. [2]
Skin cancers are cancers that arise from the skin. They are due to the development of abnormal cells that have the ability to invade or spread to other parts of the body. There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma. The first two, along with a number of less common skin cancers, are known as nonmelanoma skin cancer (NMSC). Basal-cell cancer grows slowly and can damage the tissue around it but is unlikely to spread to distant areas or result in death. It often appears as a painless raised area of skin that may be shiny with small blood vessels running over it or may present as a raised area with an ulcer. Squamous-cell skin cancer is more likely to spread. It usually presents as a hard lump with a scaly top but may also form an ulcer. Melanomas are the most aggressive. Signs include a mole that has changed in size, shape, color, has irregular edges, has more than one color, is itchy or bleeds.
Esophageal cancer is cancer arising from the esophagus—the food pipe that runs between the throat and the stomach. Symptoms often include difficulty in swallowing and weight loss. Other symptoms may include pain when swallowing, a hoarse voice, enlarged lymph nodes ("glands") around the collarbone, a dry cough, and possibly coughing up or vomiting blood.
Carcinoma is a malignancy that develops from epithelial cells. Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal or ectodermal germ layer during embryogenesis.
Penile cancer is cancer that develops in the skin or tissues of the penis. Symptoms may include abnormal growth, an ulcer or sore on the skin of the penis, and bleeding or foul smelling discharge.
Renal cell carcinoma (RCC) is a kidney cancer that originates in the lining of the proximal convoluted tubule, a part of the very small tubes in the kidney that transport primary urine. RCC is the most common type of kidney cancer in adults, responsible for approximately 90–95% of cases. RCC occurrence shows a male predomiance over women with a ratio of 1.5:1. RCC most commonly occurs between 6th and 7th decade of life.
Casuarina equisetifolia, the Australian pine tree or whistling pine tree, is a she-oak species of the genus Casuarina. The native range extends throughout Southeast Asia, Northern Australia and the Pacific Islands; including Thailand, Myanmar, Vietnam, Malaysia, Singapore, Brunei, Indonesia, East Timor, and the Philippines, east to Papua New Guinea, French Polynesia, New Caledonia, and Vanuatu, and south to Australia. Populations are also found in Madagascar, but it is doubtful if this is within the native range of the species. The species has been introduced to the Southern United States and West Africa. It is an invasive species in Florida, South Africa, India and Brazil.
Basal-cell carcinoma (BCC), also known as basal-cell cancer, is the most common type of skin cancer. It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it. It may also present as a raised area with ulceration. Basal-cell cancer grows slowly and can damage the tissue around it, but it is unlikely to spread to distant areas or result in death.
Cancer immunotherapy is the artificial stimulation of the immune system to treat cancer, improving on the immune system's natural ability to fight the disease. It is an application of the fundamental research of cancer immunology and a growing subspeciality of oncology.
Fontainea is a genus constituting part of the plant family Euphorbiaceae. The nine currently known species grow naturally in Queensland (Qld) and New South Wales (NSW) Australia, New Caledonia and Vanuatu, and Papua New Guinea. Some species are commonly named blushwood.
Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer occurring in about 3 people per 1,000,000 members of the population. It is also known as cutaneous APUDoma, primary neuroendocrine carcinoma of the skin, primary small cell carcinoma of the skin, and trabecular carcinoma of the skin. Factors involved in the development of MCC include the Merkel cell polyomavirus, a weakened immune system, and exposure to ultraviolet radiation. Merkel-cell carcinoma usually arises on the head, neck, and extremities, as well as in the perianal region and on the eyelid. It is more common in people over 60 years old, Caucasian people, and males. MCC is less common in children.
Clear-cell carcinoma also known as clear cell adenocarcinoma and mesonephroma is an epithelial cell derived carcinoma characterized by the presence of clear cells observed during histological, diagnostic assessment. This form of cancer is classified as a rare cancer with an incidence of 4.8% in white patients, 3.1% in black patients, and 11.1% in Asian patients.
Non-small-cell lung carcinoma (NSCLC) is any type of epithelial lung cancer other than small-cell lung carcinoma (SCLC). NSCLC accounts for about 85% of all lung cancers. As a class, NSCLCs are relatively insensitive to chemotherapy, compared to small-cell carcinoma. When possible, they are primarily treated by surgical resection with curative intent, although chemotherapy has been used increasingly both preoperatively and postoperatively.
Transitional cell carcinoma, also called urothelial carcinoma, is a type of cancer that typically occurs in the urinary system. It is the most common type of bladder cancer and cancer of the ureter, urethra, and urachus. It accounts for 95% of bladder cancer cases.
Axitinib is a small molecule tyrosine kinase inhibitor developed by Pfizer. It has been shown to significantly inhibit growth of breast cancer in animal (xenograft) models and has shown partial responses in clinical trials with renal cell carcinoma (RCC) and several other tumour types.
Forkhead box protein M1 is a protein that in humans is encoded by the FOXM1 gene. The protein encoded by this gene is a member of the FOX family of transcription factors. Its potential as a target for future cancer treatments led to it being designated the 2010 Molecule of the Year.
Merkel cell polyomavirus was first described in January 2008 in Pittsburgh, Pennsylvania. It was the first example of a human viral pathogen discovered using unbiased metagenomic next-generation sequencing with a technique called digital transcriptome subtraction. MCV is one of seven currently known human oncoviruses. It is suspected to cause the majority of cases of Merkel cell carcinoma, a rare but aggressive form of skin cancer. Approximately 80% of Merkel cell carcinoma (MCC) tumors have been found to be infected with MCV. Three years later, a team of researchers at the Dana-Farber Cancer Institute developed an antibody that detected MCV expression in 97% of MCC tumors. MCV appears to be a common—if not universal—infection of older children and adults. It is found in respiratory secretions suggesting that it may be transmitted by a respiratory route. But it also can be found shedding from healthy skin, and in gastrointestinal tract tissues and elsewhere, and so its precise mode of transmission remains unknown. In addition, recent studies suggest that this virus may latently infect the human sera and PBMCs.
Pembrolizumab is a humanized antibody used in cancer immunotherapy. This includes to treat melanoma, lung cancer, head and neck cancer, Hodgkin lymphoma, and stomach cancer. It is given by slow injection into a vein.
Squamous cell carcinomas (SCCs), also known as epidermoid carcinomas, comprise a number of different types of cancer that result from squamous cells. These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts.
Fontainea borealis is a small tree endemic to Papua New Guinea, in the family, Euphorbiaceae, which grows to a height of 12 m.
Fontainea subpapuana is a small tree endemic to Papua New Guinea in the family, Euphorbiaceae, which grows to a height of 7 m.
